Reaction Conditions

Reaction Steps

To a solution of 2,4-dibromothiophene (1 g, 4.13 mmol) in anhydrous ether was added n-BuLi (1.66 mL, 4.13 mmol) at −78° C. dropwise. After stirring at −78° C. for 0.5 hr, oxirane (0.32 mL, 19.28 mmol/mL in ether) was added to the reaction mixture quickly. After stirring at 0° C. for 1.5 hr, the reaction mixture was quenched with aqueous NH4Cl solution, extracted with EtOAc, concentrated and purified to give the desired product.
